Swarm of 12-15 lights with a slight orange or red glow flying at a medium slow pace to the southwest. All lights were flying at the same speed but at different altitudes. They were flying low over the horizon, from my perspective they were just above the tree tops to about 35-60 degrees moving left to right. There was no sound that I could detect that I could attribute to the lights. There were no blinking lights. There was a slight twinkle to the lights similar to the kind of atmospheric disturbance one sees with stars. A few others were standing in the street watching. I captured video of the phenomenon but cannot seem to attach it to this form. If you would like me to send the video please contact me.
